Models for chemical molecules 1 + 2

Important chemical compounds are presented in the classroom with the molecular construction kits. With the individual atoms, connecting pieces and sample instructions the ball-rod models can be made very easily by your students. These clearly show the positions of the atomic nuclei and the bonds between the atoms. Through the independent construction of the molecules, the pupils get very close to the material and keep this knowledge in a sustainable way.

The molecular models are built by simply connecting the atomic models using the connectors. Even multiple connections can be shown with the flexible connection pieces.
The color marking of the atomic species corresponds to international agreements.

By combining the individual parts of both boxes, numerous aliphatic and aromatic compounds of organic chemistry can be illustrated in the classroom.
